x86: irqflags consolidation
This patch consolidates the irqflags include files containing common
paravirt definitions. The native definition for interrupt handling, halt,
and such, are the same for 32 and 64 bit, and they are kept in irqflags.h.
the differences are split in the arch-specific files.
The syscall function, irq_enable_sysexit, has a very specific i386 naming,
and its name is then changed to a more general one.
